OrientDB-NET - CreateDatabase()

This method creates a database on the connected OrientDB Server. It then returns a boolean value to indicate that the operation was successful.

Creating Databases

When you initialize your C#/.NET application, you may find it useful to provision an OrientDB database as part of the installation process. This ensures that you'll have a database ready when you first run the application. You can create databases on the OrientDB Server by calling the CreateDatabase() method on the OServer interface.

Syntax

bool OServer.CreateDatabase(
   string name,
   ODatabaseType type,
   OStorageType storage)

• name Defines the name of the database.
• type Defines the type of database you want to create, that is a Graph, Document or Object Database.
• storage Defines the type of storage you want to use. That is, physical or in-memory.

When the operation is complete, the method returns a boolean value indicated that the new database now exists.

Examples

For instance, imagine an application that utilizes a series of in-memory databases for various services that you want to provide. You might construction a method such as this to use when provisioning new servers:

using Orient.Client;
using System;
...

// PROVISION ORIENTDB SERVER
public void InitServer(OServer server, string[] names)
{
   // LOG OPERATION 
   Console.WriteLine("Creating Databases:");

   // LOOP OVER DATABASE NAMES
   foreach(string name in names)
   {
      // CREATE DATABASE
      bool dbCheck = server.CreateDatabase(name,
         ODatabaseType.Graph,
         OStorageType.Memory);

      // REPORT CREATION 
      if(dbCheck) 
      {
         Console.WriteLine(" - SUCCESS: {0}", name);
      }
      else
      {
         Console.WriteLine(" - FAILURE: {0}", name);
      }
   }
}
